It starts from surface and we will have an extremely low strip ratio.>>> Agreed, even at .69 the oxide cap of Repressa is 3x the grade of Penasquito's oxides. Resource numbers from Goldcorp at June 07 show Oxide grades at the Penasco pit of .19 g/t, sulphides .60 and the Chile Colorado pit oxides of .18 g/t and sulphides of .25 g/t. A general look at the numbers would show that Penasquito is much lower in gold than Repressa, somewhat higher in silver and significantly higher in lead and zinc. So I think perhaps your impression of total grade might be the result of equiovalent grades based on higher base metal credits for Penasquito, instead of gold grade vs gold grade. That is why in my amateur mind I believe Repressa to be a gold mine with credits instead of a base metal mine with PM credits. Goldcorp downloads here:goldcorp.com Metates grade will be affected by the cost of liberating the ore through roasting or bio leach before recovery and it is not significantly higher than Represaa grades. <<<Independent Mining Consultants of Tuscon, Arizona using a 0.50 equivalent cut-off grade, calculated a tonnage and grade estimate of 786 million tonnes at a grade estimate of 0.81 g/t gold, 15.6 g/t silver and 0.16 % zinc for a resource inventory of 20 million ounces of gold, 394 million ounces of silver and 2.8 billion pounds of zinc.>>> .81 g/t of refractory Metates ore is not as attractive as .69 g/t of oxide at Repressa. Bottom though is we don't know enough about both deposits yet to be sure of what the final mining scenario will be. Especially the Sulphide ore at Repressa, we do not know what the recoveries will be for that ore. The oxides I think you can assume very high recovery rates of 85% - 95%. I did not realize CFO had as much delineated as you indicate. Yes, if your vision of CFO's potential is achieved as quickly as you think it just might be taken over before CPQ!!. Hope CFO updates their website soon. If they can find the tonnage to go with 134m of 2.91 g/t CFO they could build ozs very fast!! Cheers, Ogi
